SSL_CTX_flush_sessions(4/Feb/2001 (0.9.7SSL_CTX_flush_sessions(3)
NAME
SSL_CTX_flush_sessions, SSL_flush_sessions - remove expired
sessions
SYNOPSIS
#include <openssl/ssl.h>
void SSL_CTX_flush_sessions(SSL_CTX *ctx, long tm);
void SSL_flush_sessions(SSL_CTX *ctx, long tm);
DESCRIPTION
SSL_CTX_flush_sessions() causes a run through the session
cache of ctx to remove sessions expired at time tm.
SSL_flush_sessions() is a synonym for
SSL_CTX_flush_sessions().
NOTES
If enabled, the internal session cache will collect all
sessions established up to the specified maximum number (see
SSL_CTX_sess_set_cache_size()). As sessions will not be
reused ones they are expired, they should be removed from
the cache to save resources. This can either be done
automatically whenever 255 new sessions were established
(see SSL_CTX_set_session_cache_mode(3)) or manually by
calling SSL_CTX_flush_sessions().
The parameter tm specifies the time which should be used for
the expiration test, in most cases the actual time given by
time(0) will be used.
SSL_CTX_flush_sessions() will only check sessions stored in
the internal cache. When a session is found and removed, the
remove_session_cb is however called to synchronize with the
external cache (see SSL_CTX_sess_set_get_cb(3)).
